At first. Internet Explorer might be a bit glitchy, might be a little bit slow. No this is not how IE always is. It used to be, but it's not like that anymore.

As you update your computer. IE will update with it. Until you get to IE 11. Which is really fast, and really secure. Though for the time being, since this is the beginners guide. Slow and or glitchy. It's normal for IE9.
